silanisation
Silanisation is a chemical process used to modify the surface of materials, typically glass, silica, or metal oxides. It involves the reaction of a silane coupling agent with hydroxyl groups present on the surface. Silane coupling agents are molecules that possess at least one alkoxysilyl group, which can react with these surface hydroxyls, and at least one organofunctional group, which can interact with or bond to an organic material. This dual functionality allows for the creation of a stable interface between inorganic and organic phases.
The reaction typically occurs in the presence of a solvent, often water, which hydrolyzes the alkoxysilyl groups
Silanisation is widely employed to improve adhesion between dissimilar materials. For example, it is used to
